HERBERT ALLOROFT, OF PATERSON,

NEW? JERSEY, ASSIGNOR TO HOLDEN RIGBY, OF SAME PLACE.

WHIRL FOR FILLER-FRAMES.

SPECIFICATION forming part of Letters Patent No. 472,844, dated April12, 1892.

Application filed May 26, 1891.

To aZZ whom it may concern.-

Be it known that I, HERBERT ALLCROFT, of

Paterson, in the county of Passaic and State of New Jersey,have inventeda new and Improved Whirl for Filler-Frames, of which the following is afull, clear, and exact description.

My invention relates to improvements in whirls for filler-frames.

The whirl for filler-frames as commonly used is provided with a simplesocket or aperture to receive the spindle which supports the silk oryarn quill, and owing to the rapid rotation of the whirl the spindle andthe adjacent bearing portion of the whirl soon wear, so that the spindleis likely to stick and not rise easily with the quill. In this case thesilk or yarn is likely to burn or chafe and it is not wound evenly uponthe quill. Moreover, the spindle and whirl soon wear out and new oneshave to be provided.

The object of my invention is to obviate this difficulty by producing asimple form of whirl which will afford an even bearing for the spindleand which will support the spindle in such a manner that it cannotpossibly stick.

To this end my invention consists of a whirl constructed substantiallyas hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar figures of reference indicatecorresponding parts'in all the views.

Figure 1 is a broken detail view, partly in section, showing theapplication of the whirl to a filler-frame. Fig. 2 is a plan view of thewhirl, showing the splindle in section; and Fig. 3 is a similar view,but with the whirlcap removed.

In the drawings, 10 represents a portion of a filler-frame, on the upperpart of which is mounted a small stand 11, which carries the removableand conoidal friction-rollers 12, these rollers being adapted to pressevenly upon the silk or yarn which is wound upon the quill 13, and thequill is allowed to rest between the three rollers in the ordinary way.The third roller is not seen in. the drawings; but thesefriction-rollers are usually arranged in threes and their arrangement iswell understood. The above construction is of the Serial No. 394,231.(No model.)

common kind and forms no part of my invention.

The spindle 14 extends downward through the quill 13 in the usualmanner, and the rotation of the spindle serves to rotate the quill. Thelower end of the spindle is flattened and extends downward into thewhirl15, which in exterior appearance is like an ordinary 6o whirl,having a pulley 16 formed thereon, to which a belt is applied to run thewhirl. The whirl is hollow and turns on a hollow bearing 19 and isprovided at the top with a removable cap 17, having a central aperture18, through which the spindle extends.

The upper portion of the whirl is recessed internally, and pivoted inthis recess is a pair of rollers 20, which are preferably made of steelor case-hardened, so that they will not easily wear, and the spindle ll'extends down ward between these rollers, as shown in Figs.

2 and 3. It will thus be seen that the spindle will be held firmly, sothat it will revolve with the whirl and impart its motion to the quill13, and as the quill rises it lifts the spindle in the usual way and theupward movement of the spindle turns the rollers; so thata new face ofthe latter is constantly presented to the spindle, and as a resultneither the spin- 8o dle nor the rollers will be much worn. The rollersnot only prevent the wear of the spindle, but they enable it to run veryeasily, so that as the silk or yarn is wound upon the quill the spindlewill be easily raised and the 8 5 winding will be very evenly and nicelydone.

Having thus fully described my invention,

1 claim as new and desire to secure by Letters Patent I The tubularwhirl 15, provided with the pulley 16 and with a recess in its upperportion, said recess having bearings at opposite sides, two transverseparallel-spaced anti-friction rollers 20, provided with trunnions resting in the said bearings, and the cap 17, de- 5 tachably secured to theupper end of the whirl and provided with the opening 18, aligning thespace between the said rollers, substantially as herein shown anddescribed.

HERBERT ALLCROFT.
